. This invention relates to a device for folding, winding or rolling hair upon a spool provided for that purpose and heating the hair thus wound or rolled upon the spool to cause the hair to assume a more or less permanent wave or curl.

To those skilled in this art, it is well known that hair thus rolled and heated will become more or less permanently waved, and there are devices for the purpose, but it is an object of this invention to provide a means whereby two rolls of hair may be permanently waved by winding on rolls or spools, the spools securely mounted on a suitable means and the rolls simultaneously heated by a single heating unit. A further object is to provide a suitableheating unit having provision for a single heating element but two chambers into which the two rolls of hair may be inserted and means for holding the heating unit in place securely. A further object is to provide and so arrange the parts that the device is compact and convenient and easily assembled and operated, the further object beingto provide a device which will facilitate the operation and require fewer parts and less cumbersome apparatus. 7

Devices of this kind, though as compact as may be, are necessarilysomewhat cum- 3 bersome and when assembled in numbers and attached to the hair take up much room.

The device included in my invention, by heating two rolls of hair at the same time requires much less room. I j

Howl accomplish these various objects and advantages will become more apparent from the following specifications when considered in connection with the accompanying drawings, in which:

Fig. 11 is a section on the line 1111 of Referring to the drawings with more par ticularity, the device included in my'inven tion consists of a'heater, 1 having a con venient handle 2 secured to its upper face, and its lower face formed to provide two channels 3 and 4 parallel to each other and of such formas to suitably enclose each a spool and roll of hair. The heater is prefera blyconstructed of cast metal with a chamber 5 into which an electric heating element 6 is inserted and from which the cable 7 and leads 8 and 9 are conducted to a suitable source of energy. The chamber 5 is preferably closed at one end, as at 10. By the construction of thetwo channels, 3 and 4, a mid rib 11- separates the two channels and outer flanges 12 and 13 complete the form of thechannels. Upon one end of the heater, and preferably on the end of the mid rib 11, lugs 14 and 14 provide a mounting for a lever 15 having a notched edge 16 and hinged to thelugs 14 and 14 by the pin 17. A suitable spring 18 is inserted between the lever-15 and the body of the heater to urge the upward extention of the lever outwardly for an object which will presently be more fully explained. On the opposite end of the heater a fixed arm 19 is secured to the heater and has a notched edge 20 similar to the notched edge 16 of the lever 15 and similarly positioned relative to the heater. 7 A second unit of my device consists of a base .21 having channels 22 and 22' along the edges. Upon the upper face of the base and at or near the ends are plates 23 and 23 having up turned flanges 24 and 24. The edge of each plate extends beyond the end of the base to form an edge 25 and 25, seen more clearly in Fig. 7. Inserted and secured in one suitable material. At the opposite end of the base 21 hinged links 29 and 29 are inserted and hingedly secured in the end of the base.

Also hingedly attached to the links are locking levers 30 and 30 inserted between each pair of links and positioned to engage'the end of the respective clamp bars 27 and 28 to hold the clamp bars in operable position and parallel to the channels 22 and 22 of the base. The locking levers are provided with cams 31 and 31 for this purpose;

Spools upon which to wind the hair and illustrated in the accompanying drawings are more fully described in mypatent application Serial Number 470,137, and filed'July 23, 1930, and consists of a spool 32 through which the freely fitting tubular shaft 33 passes lengthwise. This tube is securely fixedat one end in" the locking head 34 and at the other'end is secured in the locking head 35 by the screw 36. This tube has a cut away portion at 37. In the spool 32 is also a cut out recess 38. The key post 39 has a 23 flanged portion 40. To the flange 40 is secured a spring pawl 41. The key post is securely mounted on a shaft 42 in which there is a stud 43 which, when the device is assembled, is positioned in the cut away place 37 of'the tube and in the cut out recess 38 of the spool. Secured to the locking head 34 is a ratchet plate 44 which is engaged by the pawl 41. On the end of the shaft 42 is a milled locking nut 45.

When the parts thus described are assembled, if the locking nut 45 is slightly released the shaft 42- is free to turn in the tube 33 and with it the key post 39 and the pawl 41 Thus the shaft may be turned to cause the pawl to engage in various of the notches of the ratchet plate 44. When the shaft 42 is thus turned in the tube it is limited in its movement by the stud 43 which engages in the cut] away portion of the tube, but the stud 43 will carry with it the spool 32, thus turning 1t a part of a revolution within the limits of the cut away opening in the tube. This opera tion is necessary to tighten the roll of'hair whichmay be wound on the spool as will be further explained.

When the parts are to beplaced'in operable position, a lock of hair is clamped between the clamp bar '27 and the base 21 and likewise a lock of hair is clampedbetween the clamp bar 28 and theopposite edge of the base 21 and each lock of hair is wound upon a spool, as shown more clearly in Fig. 3. The spools are placed in operable position by inserting the upturned flanges 24 and 24 into the spaced recesses 46 and 46 of the locking heads 34 and 35. The spools, wound with hair, are thus positioned as shown in section in Fig. 3. A protection pad 47 is then laid-over the rolls of hair and pressed down to conform to the rolls as shown in Fig. 3. The heater 1 is then laid upon the rolls as shown in Fig. 3, one roll in each of the channels 3 and 4, and pressed down upon the base 21, by which operation the lever 15 engages the edge 25 of the plate 23 and the fixed arm 19 engages the edge 25of the plate 23. The lever 15 will yield against the urge of the spring 18 sufliciently to allow it to pass by the edge 25 of the plate 23 and allow the edge 25" to engage in one of the notches of the notched edge 16. Likewise by the yielding of the lever 15, the fixed arm 19 will pass by the edge of the plate 23 and the edge 25 will engage in one of the notches 20 of the fixed arm 19. The heater 1 will thus be held firmly upon the base 21 and covering the rolls of hair, and pressing the protective pad 47 down upon the rolls of hair. 1

Thus two rolls of hair on twospools are mounted upon the one base and coveredand heated by one heater. To remove the heater, the arm 15 may be moved to disengage the notched edge 16 from the edge 25" of the plate It will be obvious to those skilled in this art that any suitable spool and means ofattaching the spools to the base may 'beused advantageously and other parts may be modified. I, therefore, do not limit my invention to the specific construction described, but claim any modification which may be in cluded within the scope of my invention.

1. A hair waving device of the character described, including in combination, a base having a channel along each of two edges, two clamping bars, one on either side of said base and each adapted to clamp a lock of hair between said bar and thechanneled edge of said base, two spools each adapted to receive and hold a lock of hair, means for attachin said spools to said base parallel to said clamping bars, and a heater having two spaced and parallel channels each adapted to receive one of said spools, and means for securing said heater to said base including a fixed arm having a notched edge and a movable lever having a notched edge, plates on said base having projecting edges adapted to engage said arm and said lever. 7
